METHOD OF PRODUCING COLORED DESIGNS.

srncrmcnrron forming part of Letters Patent No. 646,395, dated March 27, 19cc.

Application filed March 31, 1896. Serial No. 585,625. (No specimens.)

ducing such pictures having such lustrous effects resembling so-called enameled pictures; and to these ends it consists in themethod substantially as hereinafter set forth for accomplishing this result.

In carrying out the invention the material on which the picture is to be produced-i10h as paper or other materialis covered with a metallic surface, either completely or partially, in any of the well-known ways, and this surface is smoothed and polished orburnished, so that it acquires as high a luster as is possible. On the portions of the paper or other material thus prepared which are to embody lustrous metallic effects transparent colors are applied by the use of printing-plates or otherwise. These transparent colors being brought into intimate contact with the lustroushighly-glazed metallic surface or foundation the metallic luster is reflected through the transparent colors, giving them an appearance resembling enameled pictures. 3 5 These colors can then be glazed, increasing the transparencyand brilliancy, giving them a precision and depth of luster which is highly ornamental. The application, for instance,

of a clear yellow transparent color over the 0 polished or burnished metallic face produces a lustrous gold color, and other transparent colors similarly applied produce lustrous effects, and of course by the proper mixture of colors or application of them the figures or designs of the picturevmay be produced and the brilliancy of the luster of each color may be regulated and determined to meet the requirements of any particular case.

What is claimed is- O The method, substantially as hereinbefore described, of producing pictures having a metallic lustrous effect,jwhich consists in coat ing the material with'metal, polishing or burnishing the metal and then applying to said polished metal surface transparent materials, corresponding to the designs to which the lustrous metallic effect is to be given.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

GEORG THURINGER.
